Yes, if your psu can do what it claims, you will be fine.
But we don't know your psu.
We don't "trust" its specs because the total 12V wattage is low. That usually means an old design, days of different standards.
Also, more than 50% of the hardware problems resolved here are CAUSED by the PSU.
So . . . forget about 2.2 etc . . . just know that we think you should be thinking about a new, quality psu.
